Louis Gostiaux is a CNRS Researcher at the Fluid Mechanics and Acoustics Laboratory (LMFA), at École Centrale de Lyon, France. His research activities concern internal wave dynamics and stratified turbulence, both in the ocean and in the lab. From 2008 to 2011, Louis Gostiaux worked on the Coriolis Platform of the Laboratoire des écoulements géophysiques et industriels (LEGI) in Grenoble, France, the world’s largest rotating tank, now under reconstruction. In this facility, he developed a new kind of wavemaker for internal waves, which is now used by several research teams in the world. He actively works on in situ measurements in collaboration with Hans van Haren from the Royal Netherlands Institute for Sea Research (NIOZ). He participated with him to several research trips, in the Canary Basin, the Brazilian Basin and the Mediterranean Sea. This collaboration started during his post-doc at the NIOZ in 2007-2008. Before this, Louis Gostiaux defended his PhD in 2006 at École normale supérieure de Lyon, France, under the supervision of Thierry Dauxois. His PhD thesis was entitled Experimental study of internal gravity waves in the presence of topography. Emission, propagation, reflection.
